Urinary CXCL1 levels were significantly higher in the patients of IgAN (18.29 pg/mg, IQR 10.17–33.47 pg/mg) than those in patients of MCD (3.03 pg/mg, IQR 0–11.28 pg/mg, P<0.001), MN (5.89 pg/mg, IQR 0–23.54 pg/mg, P<0.001) and FSGS (6.10 pg/mg, IQR 0–17.53 pg/mg, P<0.001), while not significantly higher than those in LN (23.12 pg/mg, IQR 7.41–48.17 pg/mg, P = 0.873) (Fig. 1). Here, CXCL1 is linked to lobular neoplasia.
